“…In order to prevent further spread of the virus worldwide several businesses, factories, stores and restaurants have been closed. Consequently, an enormous number of jobs were lost or lead to short-term work, which resulted in a loss of income [11,12]. Our data reflects this process also for medical students.…”

Social context is critical in shaping behavioral responses to stimuli and can alter an individual’s behavioral type, which would otherwise be fixed in social isolation. For monogamous biparental vertebrates, social context is critical as interactions are frequent and consistent, involving high interindividual dependence and cooperation that can lead to large fitness impacts. We demonstrate that in the strictly monogamous and highly territorial California mouse, individuals alter approach response to an aggressive conspecific playback stimulus, barks, to become more similar to their partner during early bonding prior to pup birth; an effect distinct from assortative mating. Additionally, sustained vocalizations, an affiliative ultrasonic vocalization when used between members of a pair, are associated with increased behavioral convergence following pair formation suggesting a vocal communication role in emergent pair behavior. We identified the neuropeptide oxytocin as sufficient to promote behavioral convergence in paired individuals who differed in their initial behavioral type, as characterized by approach behavior. Social context, specifically pair-bonding, appears vital for behavioral responses to aggressive signals. While non-bonded animals maintained stable responses, pair-bonding led to a pair emergent property, a convergence in behavioral responses. This convergence can be driven by oxytocin, revealing a significant expansion in oxytocin’s effects on behavioral coordination.

“…Our data reflects this process also for medical students. About every fifth student was affected by such loss of income and put them under financial stress [11,12]. Therefore, the governmental decision of a financial support for students in Germany was definitely in the spirit of the students [13].…”

“…The return to habitual practice of physical activity and its link with COVID-19 is not established yet. Experts are working on protocols that prevent the virus spreading so that people may practise physical or sports activities during a lockdown due to their physical, social, psychological and cognitive benefits [75][76][77][78]. This is a crucial matter because this is not the only global pandemic we are supposedly suffering in future.…”

Analysis of Self-Concept in Adolescents before and during COVID-19 Lockdown: Differences by Gender and Sports Activity

et al. 2020

An appeal has been issued to the scientific community to investigate physical, mental and emotional states, and pro-social behaviours during the COVID-19 pandemic. Hence, this study aims to investigate adolescents’ self-concept before and during a lockdown period in relation to gender and type/amount of physical activity or sports. The pre-lockdown sample of 366 adolescents were aged 13–17 years (M = 15.51 ± 0.65), of whom 192 (52.5%) were females and 174 (47.5%) were males. During the lockdown, the age range of the sample was 13–17 years (M = 14.57 ± 1.47), of whom 82 (60.3%) were females, and 54 (39.7%) were males. The Form-5 Self-concept Questionnaire (AF-5) was used to measure adolescents’ self-concept. There was a reduction in adolescents’ overall self-concept during the COVID-19 pandemic, which was positively associated with emotional well-being, with family and peers being essential factors in the development of an appropriate self-concept. Furthermore, girls’ self-concept, especially academic self-concept, was higher than that of boys during the lockdown. However, both physical and emotional self-concept were higher for boys than girls before the COVID-19 lockdown, although no differences were found during the lockdown. The findings reveal that physical activity was positively correlated to self-concept before and during the COVID-19 lockdown.

“…Ordinary air filters have required Minimum Efficiency Reporting Value (MERV) ratings of p f = 20 − 90% in specific size ranges. Other types of free-standing filtration units (20), such as electrostatic precipitators (67) with characteristic p f values of 45 − 70%, can also be included in this framework.…”

Beyond Six Feet: A Guideline to Limit Indoor Airborne Transmission of COVID-19

The revival of the global economy is being predicated on the Six-Foot Rule, a guideline that offers little protection from pathogen-bearing droplets sufficiently small to be continuously mixed through an indoor space. The importance of indoor, airborne transmission of COVID-19 is now widely recognized; nevertheless, no quantitative measures have been proposed to protect against it. In this article, we build upon models of airborne disease transmission in order to derive a safety guideline that would impose a precise upper bound on the cumulative exposure time, the product of the number of occupants and their time in an enclosed space. We demonstrate the manner in which this bound depends on the ventilation rate and dimensions of the room; the breathing rate, respiratory activity and face-mask use of its occupants; and the infectiousness of the respiratory aerosols, a disease-specific parameter that we estimate from available data. Case studies are presented, implications for contact tracing considered, and appropriate caveats enumerated.
